Subject: linux-next: build failure after merge of the akpm tree

Hi Andrew,

After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/ethernet/qlogic/qlcnic/qlcnic_hw.c: In function 'qlcnic_prune_lb_filters':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_hw.c:607:63: error: macro "hlist_for_each_entry_safe" passed 5 arguments, but takes just 4
drivers/net/ethernet/qlogic/qlcnic/qlcnic_hw.c:607:3: error: 'hlist_for_each_entry_safe' undeclared (first use in this function)
drivers/net/ethernet/qlogic/qlcnic/qlcnic_hw.c:608:3: error: expected ';' before '{' token

Caused by commit c4b75b428da3 ("hlist: drop the node parameter from
iterators") interacting with commit 53643a75b147 ("qlcnic: fix ping
resumption to a VM after a live migration") from the net-next tree.

I applied this merge fix:
